Definitions

  • the present invention relates to a hinge device that rotatably connects two objects.
  • a hinge device is used to rotatably attach a door (rotating object) to a housing (stationary object).
  • a hinge device disclosed in Patent Document 1 Japanese Patent No. 6038968 has a first hinge body attached to an inner surface of an opening side edge portion of a housing, a second hinge body fixed to a housing side surface of a side edge portion of a door and a link mechanism interposed between the first and second hinge bodies.
  • a moving link is movably connected to the first hinge body in a front-rear direction via a front and rear connecting links. That is, a proximal end of the rear connecting link is rotatably connected to a rear end of the first hinge body (an end farther from the second hinge body), and a proximal end of the front connecting link is rotatably connected to a front end of the first hinge body (an end closer to the second hinge body).
  • a rear end of the moving link is rotatably connected to a distal end of the rear connecting link and an intermediate portion of the moving link is connected to an intermediate portion of the front connecting link so that the moving link moves in a front-rear direction as the front and rear connecting links rotate.
  • a front end of the moving link is rotatably connected to the second hinge body.
  • One end of a supporting link is rotatably connected to a distal end of the front connecting link and the other end of the supporting link is rotatably connected to the second hinge body.
  • the door rotates from a closed state so as to cover an opening side end face of the housing while a side edge portion of the door on the hinge device side moves away from the housing. Therefore, the door can be opened at a relatively large opening angle without interfering with the housing.
  • the first and second hinge bodies and the four links are made of metal, and in order to prevent the metals of these constituent members from rubbing against each other, resin spacers are interposed between the constituent members that are rotatably connected to each other. These spacers are supported by shaft members that penetrate the constituent members.
  • Patent Document 1 also shows a resin spacer interposed between the moving link and the front connecting link.
  • the first hinge body has a pair of side walls
  • the moving link has side walls of which a distance is wider than a distance between the pair of side walls of the first hinge body. Even when the moving link and the first hinge body overlap in the direction of the rotation axis, a gap is formed between the side wall of the first hinge body and the side wall of the moving link so that the metals do not rub against each other.
  • the present invention is a hinge device including a first hinge body having a pair of side walls, a second hinge body provided on a front side of the first hinge body and a link mechanism interposed between the first hinge body and the second hinge body, wherein the link mechanism including a moving link supported by the first hinge body so as to be movable in a front-rear direction, the moving link having a pair of side walls and a front end portion rotatably connected to the second hinge body, a front connecting link having a proximal end portion rotatably connected to a front end portion of the first hinge body and an intermediate portion rotatably connected to an intermediate portion of the moving link, and a supporting link having one end rotatably connected to a distal end of the front connecting link and the other end rotatably connected to the second hinge body, wherein the hinge device is configured such that the pair of side walls of the moving link overlap an outside of the pair of side walls of the first hinge body, and wherein the front connecting link has a main part
  • the first hinge body attached to a stationary object can receive the load of a rotating object via the second hinge body and the moving link, and further via the spacer so that it is possible to suppress distortion of the constituent members of the hinge device due to a gap between the side wall of the first hinge body and the side wall of the moving link.
  • the rotating object can be stably supported even if the weight of the rotating object is large.
  • the spacer is made of resin, even if the first hinge body and the moving link are made of metal, it is possible to avoid rubbing between the metals.
  • the main part of the front connecting link has a proximal end side connecting portion that enters between the pair of side walls of the first hinge body and is rotatably connected to the front end portion of the first hinge body and an intermediate connecting portion that enters between the pair of side walls of the moving link and is rotatably connected to the intermediate portion of the moving link, and at least both sides of the proximal end side connecting portion and the intermediate connecting portion are made of resin.
  • the first hinge body can firmly receive the load from the moving link while avoiding the rubbing between the metals even through the main part of the front connecting link so that the rotating object can be supported more stably.
  • both side surfaces of the intermediate connecting portion and outer surfaces of the pair of spacers are flush with each other.
  • the front connecting link supports the moving link over a wide area, it is possible to support the rotating target more stably.
  • the pair of spacers extends between the intermediate connecting portion of the main part and the proximal end side connecting portion, a pair of slits are formed between both side surfaces of the main part and an inner surface of the pair of spacers and the pair of side walls of the first hinge body enters the pair of slits.
  • the side wall of the first hinge body, the side wall of the moving link, the main part of the front connecting link and the spacer overlap each other so that the load can be borne even more firmly.
  • the main part of the front connecting link has a distal end side connecting portion that enters between a pair of side walls of the supporting link and is rotatably connected to the one end of the supporting link, and at least both sides of the distal end side connecting portion are made of resin.
  • the first hinge body can firmly bear the load while avoiding rubbing between the metals even through the main part of the front connecting link from the supporting link. Further, even if the supporting link is made of metal, the metal does not rub against each other between the front connecting link and the supporting link.
  • the entire front connecting link is made of resin and the main part and the pair of spacers are integrated.
  • the front connecting link can be easily manufactured.
  • the front connecting link includes a pair of halved members that are assembled together, an storage hole is formed between the pair of halved members, a linear damper is stored in the storage hole and a contact member provided at a distal end of the linear damper is in contact with the front end portion of the first hinge body.
